WASHINGTON (CNN) - Sarah Palin's political action committee violated federal election laws with two donations earlier this year and filed a mid-year report with a number of errors in it, according to the Federal Election Commission.

In a five-page letter to SarahPAC treasurer Tim Crawford, the FEC highlights a number of issues with the filed report, including donating more than is allowed to the reelection campaigns of Sens. John McCain and Lisa Murkowski, as well as not providing proper descriptions on how some of the PAC's money was spent.

Contacted by CNN, Crawford said the committee was currently revising the report to fix the errors and said these types of mistakes are not uncommon with FEC filings.

"A million of these [correction letters] go out every month," Crawford said. "They send out a lot of them.

A spokesman for the FEC said its standard practice for all reports to be reviewed, but would not estimate how many PAC's usually have to file corrections.

Specifically, the FEC notes SarahPAC gave $5,000 to McCain and Murkowski's primary campaigns - $2,600 more than is allowed for a PAC of SarahPAC's designation to give to a primary effort. SarahPAC also designated the donation for the senators' 2009 primary when in fact the primaries are in 2010.

To fix the error, Crawford said the PAC will allocate $2,400 to the senators' primary campaigns and $2,400 to the general election effort as is allowed under election laws. The PAC has also obtained a $200 refund from both campaigns to make up the difference.

"We essentially gave $200 too much," Crawford said. "We have since redesignated with both committees."

Crawford attributed some of the mistakes to being a new PAC and also noted FEC software that was supposed to flag mistakes when reports are initially submitted showed no errors with their filing.

"We filed what we thought was perfectly right," Crawford said. "If there is a violation, the FEC won't accept the report, but ours was accepted with no warnings or violations."
